Co-rotating twin-screw extruders have been the machine of choice for blending of polymers with additives, colorants and non-reinforcing fillers as a result of the dispersive mixing which can be achieved through selection of screw configuration and operating conditions. What does “good dispersion” mean? How do we measure/define dispersion? What factors have the biggest influence to improve dispersion quality? This webinar will introduce the basic concept of dispersive mixing in twin-screw extruders and explain the influence of operating variables on dispersion quality.
